Administer listener ports

We can use the console to administer listener ports, which each define the association between a connection factory, a destination, and a message-driven bean.

To use message-driven beans with a messaging provider that does not have a JCA 1.5 resource adapter, you cannot use activation specifications and therefore configure your beans against a listener port. There are also a few scenarios in which, although you could use activation specifications, you might still choose to use listener ports. For example, for compatability with existing message-driven bean applications.

If we have existing message-driven beans that use the WebSphere MQ messaging provider (or a compliant third-party JMS provider) with listener ports, and instead to use EJB 3 message-driven beans with listener ports, these new beans can continue to use the same messaging provider.

For more information about when to use listener ports rather than activation specifications, see Message-driven beans, activation specifications, and listener ports.

A listener port defines the association between a connection factory, a destination, and a deployed message-driven bean. If you set the initial state of a listener port to Started, the listener port is started automatically when a message-driven bean associated with that port is installed.

Listener ports can be manually started and stopped. If a message-driven bean fails to process a message several times, the listener port is automatically stopped by the application server. When a listener port is stopped, the listener manager stops the listeners for all message-driven beans associated with the port. Consequently, the associated message-driven beans can no longer process messages.

You do not usually need to start or stop a listener port manually.
